The specs provided for "Forge of Freedom" both on the box and the Matrix website currently do not indicate that the game can be played on Vista, but it does. (For some testimonies, go to this thread: http://www.matrixgames.com/forums/tm.asp?m=1990791 ) We will soon be officially supporting Vista for FOF, but until that becomes official, I figured I would unofficially indicate that FOF appears to run perfectly well on Vista, even if programmed for Windows XP.
